ATTACHMENT FOR CULTIVATORS.Y

SPECIFICATION forming part of Letters Patent No. 376,336, dated January 10, 1888.

Application filed September 9, 173587.V Serial No. 249,215. (No model.)

To all whom it may concern:

Be it known thatl, VESLEY NAVE, a citi-. zen of the United States, and a4 resident of South Haven, in the county of Sumner and State of Kansas, have invented certain new and useful Improvements in Attachments to Cnltivators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure lis a rear yiew of a cultivator-frame, showing my attachment secured thereto. Fi g.

l 2 is a side View of my attachment removed from the cultivatorfranie. Fig. 3 is a detail perspective view of the rear end of one of the cultivatorbeams, showing the several partsV separated; and Fig. 4 is a detail view of the disk.

Similar letters of reference indicate corresponding parts in all the gures.

My invention has relation to attachments for cultivators; and it consistsin the improved construction and combination of the parts of the same, as will be hereinafter more fully described and claimed.

In the accompanying drawings, the letter A denotes the wheeled frame of a cultivator having standards B, to which my improved attachment is removably and adj ustably secured.

C C indicate the longitudinally-slotted rearwardly-diverging cultivator-beams, vbent to forni inclined offsets or shoulders C C. Secured to the outer sides of two of these diametricallyopposite offsets or shoulders are posts D D, having rearwardly projecting screw-threaded projections D D', to which is secured, by means of nuts E E', an arched'bar, O, the straight ends of which are perforated, thus adj ustably connecting the cultivatorbeams. These beams are connected to the standards of the wheeled frame by screws E E, passed through the longitudinal slots R .in the beams, perforated plates G G upon the ends of said screws, and nuts vH H, forcing the plates tightly against the standards, which are placed between the plates and the inner sides of the beams, thus 'securing the attachment to the wheel-frame, removably as well as adj ustably,

inasmuch as the longitudinal slots will admit of the nuts, bolts, and plates being removed forwardly or rearwardly to accommodate various sizes of cultivatorframes, according to whether` the standards` are farther apart or 'nearer to each other. v

The inclined shoulders or offsets upon the beams have apertures I I located therein, and radial recesses above and below said apertures J and J, respectively. Threaded bolts K K are inserted through these apertures and perforated disks L, having upon one of their sides, above and below the perforations, teeth L L2, respectively, which engage theV radial recesses yin the cultivator-beams, and upon the opposite sides of these disks are recesses L3, extending entirely across the sides of the same. The disks are placed upon the bolts with their teeth engaging the radial recesses, and curved Scrapers or cultivator-blades M M, having offsets M M and apertures M2 M2 in said offsets, are secured removably in the recesses in the disks bymeans of nuts N N being screwed upon the ends of the bolts, thus forcing the teeth upon the disks iirmly in the radial recesses in the cultivator-beams and the blades tightly in the recesses in the disks. Should it be desired to adjust the blades to cut deeper in the earth, the nuts N N are loosened, and the disks are turned to the right, thus lowering the blades, and the nuts are then tightened, forcing the teeth upon the sides of the disks in the radial recesses in the cultivatorbeams, in the same manner as above described.

VMy invention is well adapted for the cultivation of corn, cotton, and small plants, and

the cultivator blades or Scrapers may be changed to throw the soil either toward or from the plant by changing the blades from one cultivator-beam to the other, and when the blades or Scrapers have become dull or worn they may be easily removed for the purpose of sharpening them or replacing them with new ones.

I would have it distinctly understood that my invention may be attached to any style of a cultivatorframe by any ordinary mechanical skill, and I reserve to myself the right to make such changes or modifications in the construction `of my device which may suggest themselves, in order to adapt it to frames of different construction, without depart-ing from the spirit of my invention.

IOO

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood. It will be seen that it is simple, strong in construction, and exceedingly e'fiicient and satisfactory in its operation.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States* 1. In an attachment for cnltivators, the combination of perforated eultivator-beams, cultivator-blades secured thereto, posts having rearwardly-proj eetingsereW-threaded projections, an arch-har the straight ends of which are perforated, and tighteningnuts.

2. In an attachment for enltivators, the combination of the standards of a wheeled frame, slotted shouldered beams, screw-thread ed bolts passing through said slots, perforated plates parallel with the slotted portions of said beams, tightening-nuts, posts secured to said beams and having rearwardly projecting screw-threaded projections, an arch-bar the straight ends of which are perforated, tightening-nuts for securing said arch-bar to the posts, and curved adj ustably-secured cultivatonblades.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

WESLEY NAVE.
